Abstract
The utility model discloses a flash evaporator, which can remarkably increase solution concentration. The flash evaporator comprises a barrel, wherein the top end of the barrel is provided with a steam outlet; the bottom of the barrel is provided with a liquid inlet pipe; the side wall of the lower part of the barrel is provided with a solution outlet; the lower part of the barrel is provided with a flash pipe; one end of the liquid inlet pipe is positioned in the flash pipe; and the outer diameter of the liquid inlet pipe is smaller than the inner diameter of the flash pipe. The flash evaporator has the advantages that: solution treated by flash evaporation is mixed with newly introduced high temperature solution, and flash evaporation is performed once again, so that the concentration of the solution is further increased.
Description
Technical field
The utility model relates to evaporimeter, refers more particularly to a kind of flash vessel.
Background technology
When solution is evaporated purification, all need to use evaporimeter, and solution can use flash vessel usually in whole evaporation technology process.Flash vessel commonly used comprises: comprise cylindrical shell, the top of cylindrical shell is provided with steam (vapor) outlet, and the bottom of cylindrical shell is provided with feed tube, on the lower sides of cylindrical shell taphole is set.The operation principle of above-mentioned flash vessel is: pyrosol enters in the cylindrical shell through feed tube, after pyrosol enters cylindrical shell, can produce a temperature difference and pressure differential with the air in the cylindrical shell, thereby make pyrosol seethe with excitement immediately and produce a large amount of steam, the steam that flashes off rises, and discharges from steam (vapor) outlet at last and makes his usefulness in addition.Solution in the flash vessel is owing to the effusion of steam, and concentration increases, temperature reduces.Enter next step operation through the solution after the flash distillation through the taphole discharge.Solution concentration after above-mentioned flash vessel flash distillation is not very desirable.
The utility model content
Technical problem to be solved in the utility model is: the flash vessel that a kind of obvious raising solution concentration is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of flash vessel, comprise cylindrical shell, the top of cylindrical shell is provided with steam (vapor) outlet, the bottom of cylindrical shell is provided with feed tube, on the lower sides of cylindrical shell taphole is set, and the bottom of described cylindrical shell also is provided with flash pipe, and an end of feed tube is positioned at flash pipe, and the external diameter of feed tube is less than the internal diameter of flash pipe.
Described flash pipe is horn-like;
Described cylindrical shell top is provided with demister;
Described taphole place is provided with downflow weir.
The beneficial effects of the utility model are: utilize the solution after the flash distillation to mix with the pyrosol that newly advances, and carry out flash distillation once more, thereby further improve the concentration of solution.
Description of drawings
Fig. 1 is the structural representation of the utility model flash vessel.
Among the figure: 1, cylindrical shell, 2, steam (vapor) outlet, 3, feed tube, 4, taphole, 5, flash pipe, 6, solution channel, 7, downflow weir, 8, demister.
The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Figure 1, flash vessel described in the utility model, comprise cylindrical shell 1, the top of cylindrical shell 1 is provided with steam (vapor) outlet 2, and the bottom of cylindrical shell 1 is provided with feed tube 3, and taphole 4 is set on the lower sides of cylindrical shell 1, the bottom of cylindrical shell 1 also is provided with the flash pipe 5 of bell mouth shape, and an end of feed tube 3 is positioned at flash pipe 5, and the external diameter of feed tube 3 just forms solution channel 6 less than the internal diameter of flash pipe 5 between feed tube 3 and the flash pipe 5.For the liquid level that guarantees solution with prevent from not have the solution of abundant flash distillation to discharge from taphole, 4 places are provided with downflow weir 7 at taphole.Demister 8 is set on the top of cylindrical shell 1 can obtains clean steam, better utilization steam.
Operation principle of the present utility model is: pyrosol enters flash pipe 5 through feed tube 3, in flash pipe 5 enters cylindrical shell 1 time, pyrosol carries out flash distillation above the flash pipe 5 upper end mouths of pipe, the steam of generation is discharged from steam (vapor) outlet 2 after demister 8 foam removals.And just enter cylindrical shell 1 bottom through the solution after the flash distillation, continuous increase along with the solution after the flash distillation, liquid level of solution constantly rises, the flow velocity of solution in the control feed tube 3, make liquid level of solution be higher than the mouth of pipe of flash pipe 5, liquid level of solution is as effective flash distillation area maximum of flash distillation liquid level so at this moment, and flash efficiency is the highest.Because solution level is higher than the height of downflow weir 7, the solution that exceeds after the abundant flash distillation of downflow weir 7 height is discharged from taphole 4 through downflow weir 7.The solution of cylindrical shell 1 bottom just enters in the flash pipe 5 from the solution channel 6 between flash pipe 5 and the feed tube 3, and and the pyrosol of newly coming in mix, following pyrosol then rises together, and the liquid level of solution place above the flash pipe 5 upper end mouths of pipe carries out flash distillation again, thereby further improve the concentration of solution, and the like, after flash distillation repeatedly, solution concentration obviously improves.When liquid level of solution surpassed downflow weir 7, fully the solution after the flash distillation was just discharged from taphole 4 through downflow weir 7.
